What this service covers
A webhook is an event notification sent by one service to another over HTTP. It can reduce polling and latency, but delivery time still depends on the sender, network, and queue load. Webhooks should not be treated as guaranteed real-time or lossless delivery.
Incoming handlers can verify signatures and timestamps, reject duplicates using event identifiers, and place work on a queue. Outgoing deliveries can use limited retries, backoff, and a dead-letter queue. These controls reduce risk but cannot recover an event the provider never sends without reconciliation.
Events can trigger defined payment, order, or form workflows. For financial operations, the webhook should not be the only source of truth; periodic API reconciliation and administrator review are advisable. Provider accounts, licenses, fees, and data permissions remain the client's responsibility.

Frequently asked questions
What is the difference between a webhook and a REST API call?
An application calls a REST API when it needs data or an action. With a webhook, the provider sends a notification after an event. Webhooks still need retries, logging, and reconciliation.
How do you verify an incoming webhook?
Where supported, I validate the provider's signature, timestamp, and event identifier. Source-IP restrictions and secret rotation may also be added, subject to the provider's mechanisms.
What happens if a webhook is not delivered?
Limited retries, dead-letter handling, and alerts can manage known failures. For critical events, periodic API reconciliation helps find missing records; absolute delivery cannot be guaranteed.
